I generally co-wash but nothing beats a good cleansing session to get rid of buildup and excess oil. For me, shampoos tend to dry my hair out even the sulfate free ones. However, Bentonite clay gets rid of the impurities all while keeping my hair moisturized. Bentonite clay consists of aged volcanic ash and has the ability to absorb toxins, impurities and chemicals. It is one of the most powerful clays for detoxing.
How to make a clay wash
2TBS Bentonite Clay
1TBS Apple Cider Vinegar (great for clarifying)
1TBS of olive oil - To moisturize
10 drops Tea Tree oil - Cleansing agent
1tsp Vitamin E oil
Mix until smooth then apply to damp hair massaging into the scalp first then rubbing the mixture along the length of your hair. Leave it on for 15 minutes covering with a plastic cap. Be sure to use a plastic cap to ensure that the clay does not dry in your hair. If the clay dries it may be more difficult to rinse out.
